The solution is, Option B Negative ,as time passes, speed decreases.

Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.

Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.

here, we have,

Description of the Graph

1. The Relation between , Speed and time is depicted on the graph.

2. Minute = x coordinate

Miles per hour= y coordinate

The points shown on the graph , describing the relationship are, (5,15),(10,13.8),(15,11),(20,10),(25,9.8).

There are two types of Correlation

Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.

Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.

As you can see from the points plotted on the graph ,with increase in x value , y value decreases.

So it is negative correlation.

As, time passes, Speed Decreases, So it is a Negative Correlation.

Option B  Negative ,as time passes, speed decreases.

Step-by-step explanation:

30 , 60 , 90 , 120, 150

,LCM of 12 and 30 is 60

Answer:

List the first five multiples of 30

The first 5 multiples of 30 are: 0, 30, 60, 90, 120.

What is the lowest common multiple of 12 and 30

for LCM (12,30) we find:

Prime factorization of 12 = 2 × 2 × 3.

Prime factorization of 30 = 2 × 3 × 5.

Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.

Therefore LCM (12,30) = 60

Answer:

40kg

20kg

10kg

Step-by-step explanation:

The computation of the food each one is getting as follows

Total weights of all dogs

= 20 kg + 10 kg + 5kg

= 35 kg

And, the food is 70 kg

So, each one is getting

for 20 kg

= 70 ÷ 35 × 20

= 40 kg

For 10 kg

= 70 ÷ 35 × 10

= 20 kg

And, for 5 kg

= 70 ÷ 35 × 5

= 10 kg

Answer:

67 ÷ 9 = 7.444

wait i got it!

Since 18 kilograms are 18000 grams, you have

18000/30=600

and

800/30=26.6

So, with 18 kilograms of salt the baker can make exactly 600 batches with no leftovers, while with 800 grams of salt the baker can make 26 batches, with some leftovers.

In fact, 26 batches require

26 x 30 =780

grams of salt, and the remaining

800-780=20

grams of salt are not enought to prepare the next batch

Answer:

30

Step-by-step explanation:

(x + 37) + (x + 67) + 90 = 180 by the Triangle Angle Sum Theorem

(x + 37) + (x + 67) = 90

2x + 104 = 90

2x = -14

x = -7

(-7 + 37) = angle A

angle A = 30

Answer:

<a = 30

Step-by-step explanation:

x + 37 + x + 67 + 90 = 180

<A + <B + <C = 180

*take each angle, add them, and equal them to 180*

x + 37 + x + 67 + 90 = 180

*solve for x*

2x + 194 = 180

      -194   -194

2x = -14

x = -7

<a = x + 37

<a = (-7) + 37

<a = 30

<b = x + 67

<b = (-7) + 67

<b = 60

<c = 90

Step-by-step explanation:

Head opposite angles

2x= 3x-42

x= 42°

the angles are 84°

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x is 42 and the measure of the two given angles is 84° each.

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.

The two of the given angles are vertically opposite angles, therefore, the measure of the two given angles will be the same.

(2x)° = (3x - 42)°

2x = 3x - 42

Subtract 2x from both sides of the equation and add 42 to both sides of the equation,

2x - 2x + 42 = 3x - 42 - 2x + 42

42 = 3x - 2x - 42 + 42

42 = x

Therefore, the value of x is 42. Now, the measure of each angle can be written as,

(2x)° = 2(42) = 84°

(3x - 42)° = 3(42) - 42 = 84°

Hence, the value of x is 42 and the measure of the two given angles is 84° each.
